tracing: Some micro optimizations

Andi Kleen pointed out a trace that showed lots of functions being called in the trace event hot path. These functions would help to be inlined. More needs to be done, but this is just a start.

Steven Rostedt (Red Hat) (8):
tracing: Create a always_inlined __trace_buffer_lock_reserve()
ring-buffer: Make rb_reserve_next_event() always inlined
ring-buffer: Always inline rb_event_data()
tracing: Make tracepoint_printk a static_key
tracing: Make __buffer_unlock_commit() always_inline
ring-buffer: Force inline of hotpath helper functions
ring-buffer: Froce rb_update_write_stamp() to be inlined
ring-buffer: Force rb_end_commit() and rb_set_commit_to_write() inline
